As many as 1,500 buses across Canada are fitted with the part. The warning has prompted a transit service in the Gatineau region to take dozens of its vehicles out of service.

Eighty-eight of the TTC’s articulated buses are affected by the recall. But, for the moment, transit service won’t need to pull any off the road, spokesman Brad Ross said. He called the recall "precautionary."

The fire risk, he said, increases when the vehicles are at least a few years old. Toronto’s models, which run primarily on the 7 Bathurst and 29 Dufferin routes, went into service last December.

“It’s something that has only been seen in the older bus fleets. But, nevertheless, we will [be] checking the fleet,” said Ross.

“It is a very low risk,” he said later.

The TTC hasn’t received the recall notice yet, but Ross said the transit commission will be working with Nova to inspect the condition of the cable in question.

“They are going to be inspected for any wear on this particular cable If there is no wear on this particular cable, then it won’t require any repairs at all.
